Our aim
We follow the WCAG 2.2 guidelines at level AA: enough contrast in light and dark, everything usable with the keyboard and a clear focus.
Diagrams and pictures
Every interactive picture has sliders or buttons that work with the keyboard, and a line of text that says what the picture shows. Colour never stands alone: made-up parties also have a letter, and every marker a name or an icon. Feedback on exercises is always in words and with an icon.
Reading comfort
With the button showing a small figure at the top of every page you pick a profile in one tap (low vision, colour blind, reading is hard, hard of hearing, keep it calm) or choose what helps yourself: larger text, more or high contrast, colour correction, a big cursor, more spacing, a readable font, underlined links, a reading guide, read aloud with your device's own voice, captions without sound and less motion. Your choice stays on your device and goes nowhere. The button replaces nothing: the website also works without it, together with your own device's settings.
What could be better
On a narrow screen the learning path is a list rather than a map. Some pictures are quicker with a mouse or a finger than with the keyboard, but everything works with the keyboard.
